Amy Winehouse Back in London – to Face Divorce?

Amy Winehouse is back in the U.K. – with an old hairstyle and a new life.

The singer, 25, arrived early Sunday, sporting her trademark beehive, which replaced the curly mop she had worn during her near three-month extended vacation on the Caribbean island of St Lucia.

And while the hair was back, she has a fresh start ahead of her. Soon after her plane landed at London's Gatwick Airport, Winehouse received a tour of her new home on the northern outskirts of London by her father Mitch, and they spent much of the afternoon watching their soccer team Tottenham Hotspur lose to Manchester United.

"As she said when she got back, 'I love London more than anyone else,'" a source close to Winehouse tells PEOPLE. "She missed London. She's fine."

But there is also the issue of her marriage to sort out, as estranged husband Blake Fielder-Civil moves towards divorce in January.

To the delight of his family, Fielder-Civil was freed from jail late last week after serving his sentence on charges of assault and attempting to pervert the course of justice.

A source tells PEOPLE that the couple have not seen each other since the singer's return. Winehouse has said she's determined not to let Fielder-Civil divorce her, but a source close to him vows to PEOPLE that it will go forward. Her rep, Chris Goodman, has heard nothing official on the possible marriage breakup.

As for a report in the Sun tabloid that Winehouse got into a fight with a fellow passenger on her flight home, a source close to her dismisses it saying, "There was some banter, that's all."
